Abstract Symmetry-based selection rules are developed providing minimal criteria for the existence of two-channel Kondo interactions between conduction electrons and the low energy degrees of freedom on U 4+ and Ce 3+ in a metal host, assuming that the underlying microscopics are regulated by the Anderson Hamiltonian. An additional dynamic selection rule is imposed on Ce 3+ ions. The selection rules restrict the two-channel quadrupolar Kondo effect to U 4+ ions in cubic, tetragonal and…

The two-channel Kondo route to non-Fermi-liquid metals
We present a pedagogical and critical overview of the two-channel Kondo model and its possible relevance to a number of non-Fermi-liquid alloys and compounds. We survey the properties of the model,
Kondo Effect in Systems with Two-Electron Occupancy
The Kondo problem of systems with two-electron occupancy in a realistic crystalline electric field (CEF) is investigated using the numerical renormalization group method. We examine the ground state
Phenomenology of two channel Kondo alloys and compounds
Abstract We report realistic calculations of magnetic response and transport coefficients for a model U 4+ ion in a metal which undergoes the quadrupolar Kondo effect. We find a small critical regime
Competing Kondo Effects in Non-Kramers Doublet Systems
In non-Kramers Kondo systems with quadrupolar degrees of freedom, an ordinary magnetic Kondo effect can compete with the quadrupolar Kondo effect. We discuss such competition keeping PrT2Zn20 (T =
Stability of non-Fermi liquid in Kondo effect due to (5f)2configuration
The stability of the non-Fermi liquid (NFL) in Kondo effect is studied by considering the excited states of the 5 f -electrons. First, in order to examine their effects in the strong correlation
Cubic hastatic order in the two-channel Kondo-Heisenberg model
Materials with non-Kramers doublet ground states naturally manifest the two-channel Kondo effect, as the valence fluctuations are from a non-Kramers doublet ground state to an excited Kramers
Kondo Effect Due to Impurities with (5f)n Configuration: Fermi Liquid Versus Non-Fermi Liquid
The Kondo effect due to U-type impurities is studied in connection with the stability of the Fermi liquid and the non-Fermi liquid. First, an effective exchange Hamiltonian in terms of irreducible
Competition between Quadrupole and Magnetic Kondo Effects in Non-Kramers Doublet Systems
We discuss possible competition between magnetic and quadrupole Kondo effects in non-Kramers doublet systems under cubic symmetry. The quadrupole Kondo effect leads to non-Fermi-liquid (NFL) ground
Single-ion scaling of the low-temperature properties of f-electron materials with non-Fermi-liquid groundstates
Certain chemically substituted Ce and U compounds have low-temperature physical properties that exhibit non-Fermi-liquid (NFL) characteristics and apparently constitute a new class of strongly
Crystal distortion and the two-channel Kondo effect
We study a simple model of the two-channel Kondo effect in a distorted crystal. This model is then used to investigate the interplay of the Kondo and Jahn-Teller effects, and also the Kondo effect in

Full-scale numerical-renormalization-group calculations on the anisotropic, two-channel, impurity spin {ital s}=1/2 Kondo Hamiltonian confirm the approach to a nontrivial fixed point from weak coupling, the stability of the fixed point against exchange anisotropy, and the destabilized point by the application of a magnetic field or the lifting of exchange symmetry.
Critical theory of overscreened Kondo fixed points
The low-temperature fixed point of the Kondo model, for k bands and a spin-s impurity, is well understood by Nozieres' Fermi liquid theory for k ⩽ 2s. However when k > 2s, a new type of non-trivial

Measurements of electrical resistivity ρ (T), specific heat C(T), entropy S(T, and magnetic susceptibility χ(T) as functions of temperature T for the alloy system Y 1-x U x Pd 3 suggest that ΔS(O)≃(R/2)ln(2) and ΔS (O)∼-ln(aT) are close to saturate.

Universal noninteger "ground-state degeneracy" in critical quantum systems.
G is argued to decrease under renormalization from a less stable to a more stable critical point and plays a role in boundary critical phenomena quite analogous to that played by c, the conformal anomaly, in the bulk case.
